As previously stated, the oil which is fed through the opening 20 lubricates the wall of the cylinder and this oil is received in grooves 44 and 46 below and above the wrist pin 48. The wrist'pin bushings are, of

course, lubricated by the oil which enters the larly' shaped and secured by screw bolts or other suitable means to the lower end of the cylinder.

A portion of theoil which is pickedup by the finger or pickup device 11 will splash againstth wall of the crank case and it will drip into a ledgeor gutter 55 formed integral with the crank case and discharging into anopening orpocket 56 above one of the ,main hearings in the engine. The oil thus received'in the pocket 56 is utilized to lubricate the adjacent main hearing as a suitable passage 58 may be provided to, allow the oil to flow from the pocket to, the main Fig. 1 illustrates that alnbricant collect ing ledge 60, is positioned directly beneath the-valve .24: and a; shoulder w62;a-ndcollects the oil which drips from these parts so as to lubricate the'other main hearing. The oil which is received in the ledge 60 enters a pocket 63 andlubricates the adjacent Ina-in i hearing. It is thus seen that both themain bearings are; thoroughly lubricated.

With reference to the. foregoing descriptiontaken.;.in connection with the; accompanying drawing it will. be seen that a lubricating system constructed in accordance with this invention may be employed without a separate pump. 7 .Orif; desired a pump may be employed.

The supply of oil to the cylinder may be conveniently regulated by the opeltatol? Without special skill since :it is merely necessary to. turn thehead30; by handor otherwise to position the proper opening=25 in registration theopening" 15. The invention vmay be carried out in connection with a single, or multiecylinder engine,
